    The problem with dividing in half is I ended up going from 20kpa idle to 40kpa wot so not enough roof for adjustments so I?m playing with the map scale still to try to get my fuel map as large as I can without going over 105

    This is by far the most aggravating pcm iv had to mess with iv tuned many all motor and boosted LS?s and a few coyotes but this by far beets them all..your just very limited to what you can do with them and nobody knows much about them so with everything else there 1000 people that have done the same thing your doing but not with this...but that?s what makes it fun

    Don't forget you need to eliminate baro correction....
    If in doubt, multiply everything by 1.1.
